Available Interface Submodules

Note

Only use interface submodules that are explicitly released for use in S7-400 devices.

Installing Interface Submodules

!Warning

The modules can be damaged.

When inserting or removing interface submodules with power applied, the CPU and interface submodules can be damaged (exception: using synchronization submodules in an H system).

Never insert or remove the interface submodules while power is being supplied (exception: synchronization submodules). Always switch off the power supply before inserting or removing interface submodules.

!Caution

Danger of damage to persons and property.

Interface submodules contain electronically-sensitive components that may be damaged if they are touched.

The surface temperatures on the components can reach up to 70o C and there is a risk of burning.

For this reason, you should always hold the interface submodules on the longest sides of the front panel.

Observe the ESD guidelines when installing interface submodules.
